What is the best recommendation for a 46-year-old female with type-I diabetes who has difficulty sleeping during daytime hours due to working overnight shifts?

From the Guidelines

For a 46-year-old female with type-I diabetes who has difficulty sleeping during daytime hours due to working overnight shifts, I strongly recommend implementing a comprehensive sleep hygiene approach combined with timed melatonin supplementation, as this approach has been shown to improve sleep quality and glycemic control in individuals with diabetes.

Key Recommendations:

• Take 1-3 mg of melatonin about 2-3 hours before the intended daytime sleep period, as supported by the most recent guidelines 1.
• Create a dark, quiet sleeping environment using blackout curtains, eye masks, and earplugs or white noise machines to promote better sleep.
• Maintain a consistent sleep schedule even on days off to help regulate the circadian rhythm, which is crucial for individuals working night shifts 1.
• Monitor blood glucose levels carefully, as shift work can disrupt glycemic control in type-I diabetes, and consider adjusting diabetes management strategies as needed 1.
• Avoid caffeine at least 6 hours before sleep and limit screen exposure 1-2 hours before bedtime due to blue light's suppressive effect on melatonin production.
• Regular exercise can improve sleep quality, but avoid vigorous activity within 3 hours of sleep time, as it may interfere with sleep onset.

Rationale:

The associations between sleep problems and diabetes are complex, with sleep disorders being a risk factor for developing type 2 diabetes and possibly gestational diabetes mellitus 1. Sleep disturbances are also associated with less engagement in diabetes self-management and may interfere with achieving glycemic targets among people with type 1 and type 2 diabetes. Given the potential for sleep disruptions to worsen insulin sensitivity and glycemic control, prioritizing sleep hygiene and considering melatonin supplementation is essential for managing type-I diabetes in the context of night shift work 1.

Considerations:

• It is essential to consider the individual's specific sleep-wake schedule and adjust the timing of melatonin supplementation accordingly to maximize its effectiveness.
• Regular follow-up with a healthcare provider is necessary to monitor the effectiveness of these recommendations and adjust the treatment plan as needed to ensure optimal glycemic control and sleep quality.
